I IMPROVEMENT IN ATTACHl-NG LAMP-FO UNTS TO BRACKETS, CHANDE LIERS. 800.

The Schedule referred to in these Letters Eaton.- and making part of Hie same.

To allwhom tit-may concern:

Be it known that I, GEORGE BOHNER, of Chicago, in the county of Cook and State of Illinois; have invented a new and useful Method of Attaching Lamp- Founts to Brackets, Chandeliers, &c.; and Ido hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being bad to the accompanying drawing forming part of this specification. .'Figure l is a vertical section of a lamp-fonnt or reservoir attached to a bracket.

Figure 2 is a perspective view of the device for at,- taching the fount to the bracket;

Figure 3 is a similar view of a modification.

Figure 4 is a longitudinal section of fig. 3.

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

Lamp-founts have heretofore been attached to brackets by means of a screw-ferrule adapted to screwupon a short metallic projection cast uponthe end of a bracket, anda similar projection or stem formed upon the under side of a lamp-fount. By this method, however, ibunts cannot .be attached to old brackets, .hut the latter must be specially constructed for the purpose.

My invention has for its objecttoprovide simple and economical means for attaching a lamp-fouut to old brackets or chandeliers, or those of ordinary construction, so that persons desirous of attaching founts to brackets already in use shall not be compelled to incur the additional expense of new brackets; to this end,

The invention consists in constructing the screwferruie in such a manner that, while it receives the projection upon the lamp-fount, it shall also be capable of screwing directly upoh the ends of brackets and chandeliers of ordinary construction, or upon a short nut or block adapted to fit both the ferrule and the end of the bracket.

In the accompanying drawing- A is a lamp-fount or reservoir, and

B, the arm of abracket orchandelier, provided with the screw-pin or projection 6 upon its outer end in the ordinary manner.

I) is a short metallic ferrule, provided with a spun In figs. 3 and 4 the screw-ferrule is shown cylindrical in form, and adapted to receive at its lower end a short recessed nut or block, G, of metal or other proper material.

The nut is attached to the ferrule by a screw-connectiou, and its recess His provided with a femalescrew thread, by which the nut is secured to the braoket-pin O, as will be readily understood.

The nut may be made with an opening extending entirely through it, instead of a recess, it found prei erable.

By my invention a medium of connection is formed between a lamp-fount and a bracket or chandelier without constructing the latter specially for the purpose. lounts can, therefore, be easily applied to bracket-s at but trifling expense. I

I do not claim the cylindrical screwesockets shown in figs. 3 and4, as they are not of my invention; but

What I do claim, and desire to secure by Letters Patent, is

1. A screw-ferrule, constructed in sucha manner as to connect a lamp-fount or reservoir to an ordinary bracket or chandelier, substantially as herein described, for the purpose specified.

2. The metallic screw-ferrule I), constructed as described, with one end contracted to fit upon ,the ordinary screw-pin of a lamp-bracket or chandelier, for the purpose specified.

3. The nut or block G, constructed as described, to connect-the cylindrical lamp-ferrule to the screw-pin of a lamp-bracket or chandelier, as herein set forth,

for the ,purpose specified. v
